LACEETA MUEALIS IN WESTERN" EUEOPE AND NOETH AEEICA. 407 



Scales on upper surface of tibia as large as or a little smaller than dorsals, keeled ; 

 18 to 28 femoral pores on each side, usually 21 to 25 ; 27 to 34 lamellar scales under 

 the fourth toe, usually 30 to 33. 



Caudal scales truncate, upper rather strongly keeled, 30 to 37 in the fourth whorl 

 behind the postanal granules. 



Brown, olive, or green above, usually spotted or marbled with blackish and with a 

 yellowish or whitish dorso-lateral streak or series of spots ; frequently a blackish 

 vertebral streak or series of spots ; sides, in males, usually blackish, with numerous 

 round light spots ; females frequently uniform yellowish brown or mahogany-brown on 

 the back, with a yellowish, black-edged dorso-lateral streak from the eye to the tail, 

 and another, wider, light streak from the ear to the groin (PI. XXIX. fig. 2) ; limbs 

 with round, dark-edged, light spots. Lower parts white or yellow, without or with black 

 spots, which are usually confined to the throat and the outer row of ventral plates. 

 According to Lorenz Muller, the lower parts are sometimes bright orange in males. 



The following notes are taken from living specimens from Sardinia, for which I am 

 indebted to Count Peracca, and three of which are figured (PL XXIIL fig. 4, & 

 PI. XXIX. figs. 1, 4). 



. Coppery brown, yellowish brown, greenish yellow, or bright green above ; white, with 

 mother-of-pearl sheen, or greenish yellow beneath ; turquoise-blue spots always present 

 above shoulder and on outer ventral plates ; some specimens with numerous blue spots 

 on the sides, alternating with green or greenish-yellow ones ; the dorso-lateral streak 

 pale brownish or greenish yellow. 



Specimens in which the black markings preponderate, the light ground-colour 



appearing as four dorsal lines with small spots or cross-lines between them, have been 



named by Bedriaga var. Corsica (PI. XXIX. fig. 3).
